Well there is an option to strip color and stuff but that's not you're looking for.

You'd need an on text event that removes all italics, like so.

on ^*:text:* *:#: echo $color(normal) -mt $chan $+(<,,$nick($chan,$nick).color,$iif($left($nick($chan,$nick).pnick,1) isin $prefix,$v1),$nick,>) $remove($1-, )

Have your friend try that out and tell him I think he's crazy also, lol.
